no TopFlix. A new documentary film revisits the golden age of kung fu stuntmen and action directors in Hong Kong during the 1960s-'80s, exploring their pain and struggles. The documentary is a tribute to kung fu stuntmen. “They risked their lives for stunts,” said kung fu choreographer Yuen Bin. In their heyday, these stuntmen and choreographers presented the best, most creative and most complicated kung fu fight sequences anywhere in the world, creating stunts that looked seemingly impossible.
